Keep the bit parallel to the nail, shape, smooth uneven areas, clean cuticles and buff afterward.
Never use the e-file on skin, take breaks to prevent overheating
Most e-files use a standard 3/32” shank, so ensuring compatibility is the first step. Using the correct size guarantees a secure fit, smoother operation, and safer use during manicures or pedicures.
Different materials are designed for different purposes and skill levels.
Each shape serves a specific function and helps improve accuracy.
Grit determines how coarse or fine the bit is, which affects how much material it removes.
Choosing the right combination of material, shape, and grit based on your specific task ensures better results. This not only improves efficiency but also helps protect the natural nail and enhances overall safety.
Maintain bits by brushing off dust, wiping with alcohol, and deep cleaning with disinfectant after use. Sterilize reusable bits via autoclave, UV sterilizer, or disinfectant, store them in organizers, and replace dull, cracked, or worn bits every 3-6 months with regular use. Avoid dropping bits or using them on hard surfaces.
Troubleshoot issues: tighten loose bits or replace incompatible/worn parts for slipping; reduce pressure, use proper grit, and adjust angle for nail damage; lower speed, take breaks, and clean bits for overheating; replace dull bits or adjust grit/speed for poor performance; prioritize sanitization to prevent skin irritation.
